CC -!- FUNCTION: Polygalacturonase required for degrading the pollen mother
CC cell wall during microspore development. {ECO:0000269|PubMed:14551328}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(1,4-alpha-D-galacturonosyl)n+m + H2O = (1,4-alpha-D-
CC galacturonosyl)n + (1,4-alpha-D-galacturonosyl)m.; EC=3.2.1.15;
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall
CC {ECO:0000269|PubMed:14551328}.
CC -!- TISSUE SPECIFICITY: Expressed in the tapetum cells in the anthers and
CC in the ovules of open flowers. {ECO:0000269|PubMed:14551328}.
CC -!- DEVELOPMENTAL STAGE: Transiently expressed during the early microspore
CC stage. {ECO:0000269|PubMed:14551328}.
CC -!- DISRUPTION PHENOTYPE: The mature pollen grains are arranged in a
CC tetrad. A layer of material is frequently deposited on the surface of
CC the distal region of the pollen grains. {ECO:0000269|PubMed:14551328}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 28 family. {ECO:0000305}.
